Possible Sempervivum flower?

I planted a Sempervivum in my Belfast sink and this flower has appeared in the last few days.....I didn't think it was a flowering type so my question is, does the flower belong to the sempervivum or is it a different plant and if so what is it?

This is a better picture of the Sempervivum, it is a bit hidden by the Geum at the moment.

Oh, wow, I didn't realise. I thought the cobwebby thing on the plant was the 'flower'. It must like it in the sink underneath the Geum I'll have to make sure Lily sees this thread as she liked the sempervivum when I bought it.

'The one at the bottom with what looks like cobwebs on it is yes, the one I bought yesterday. Is it a type of Sedum? The label says Sempervivum (Arachnoideum), it has an RHS Garden of Merit award They are so pretty. Your pot looks lovely Lily....for an Alpine garden'

I can't believe how much they have all filled out so quickly, I might post some more pics on that thread

Hi Star gaze I think the plant in your photo is an echeveria, I have 4 different ones. Like sempervivums they can cope with drought but I find they grow much better if kept watered, they aren't frost tolerant either. Here in the NE I overwinter mine in a cold greenhouse. They are also propagated from off shoots.

Yes its funny OL, i never really liked them much either, but saw the ones i got for the pot and really like them now, tho there are still some that i don't think are that great. Hope that makes sense lol.

Thank you OL, its got more flowers on it since that pic was taken, and theres another just starting to poke through. Just wondered if it should come inside for the winter, its quite big and I don't want to lose it.
